The literature relating to this area provided a practical framework for constructing the IWBAS (Teo, 2010; Turel, 2011; Sad, 2012; Venkatesh et.
The IWBAS consisted of a four-point Likert scale with responses ranging from "strongly disagree" (1) to "strongly agree" (4).
In order to develop a valid and reliable IWBAS, close examinations of the factor structure and psychometric properties of the items were conducted.
A principal component analysis (PCA) was carried out to examine and compute composite scores for the constructs underlying the IWBAS. It is common to assess the factorial validity of the scale used in a research project, and prior to conducting the principal component analysis it is sound practice to appraise the suitability of the dataset.
After the dataset was assessed for its factorability, the 14 items of the IWBAS were subjected to factor analysis.
In addition to the factorial validities, the convergent validity and discriminant validity of the IWBAS were examined through inspection of the average variance extracted (AVE) and discriminant validity.
It took each participant approximately 20 minutes to complete the IWBAS. The survey consisted of 14 items and participants were requested to select their responses from a four-point scale.
Despite the results indicating that the IWBAS is reliable and valid, some primary limitations mirror the need for further investigation.
